Retsch's rotor mills cater to a wide range of materials, from food ...
As shown in Table 2, PFI milling, grinding, and ball milling all reduced the DP of BSKP significantly. Among them, PFI milling had the least effect on DP reduction because this treatment was highly uneven and still retained many original plant fibers (see Fig. 4a). For the other two pretreatments, 4 h of ball milling resulted in the most severe ...
Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.
Over a range of mill speeds (about 40 – 60 of mill critical speed for rod mills and 50 – 70 : of mill critical speed for ball mills), the holdup is approximately constant but at rotational speeds above or below this range, the holdup increases sharply.
